Worst thing I've ever seen was when my dog's anal glands burst, and went right through the skin. There I was with a dog with one old asshole, and one new one. If you know anything about anal gland fluid, you know it is the smell of hell.
If your dog's anal glands ever burst, the proper treatment is to take the dog outside and irrigate the wound thoroughly with the garden hose. Set the dog on top of half a dozen old towels and drive it to the vet ASAP, where you will get bumped immediately to the front of the line. Vet will check the wound, probably leave it alone and give doggo some antibiotics and maybe some sedatives to help him sit still and rest.
Go home and drink heavily, because you need some sedatives at that point, too. The next day, learn about how to properly express your dog's anal glands so neither of you end up in this situation again.
